Abstract
Block-form cleaners for flush toilets which consist of at least two masses of different composition, one of the masses being at least partly surrounded by the other mass(es) and the surrounded mass containing an active substance in a concentration at least 1.3 times higher than in the surrounding mass. This distribution ensures that the active substance is more uniformly released over the useful life of the cleaning block.
